E39 (1997 - 2003) The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

The problems continue with my 540i/6... All of a sudden he refuses to rev higher than 800-1200 rpm, no matter how far u press the pedal... Otherwise there are no other symptoms, except perhaps that I think it is ticking a little from this section:http://imageshack.us/photo/my-images/832/bmwm62b44.jpg/

Yes, that is a purge valve for the charcoal canister that is above the left rear wheel liner.
It has nothing to do with why your engine won't rev.
Have you checked the ACS throttle body that is just past the MAF to see if it is fully open?

I believe that device is the purge valve for the vapor recovery system, and I think it buzzes periodically. Mine doesn't have one like that.

I dont have any codes at the moment. Alright then i exclude that it may cause a problem!

The translate of "charcoal canister" doesent give any results for me. Is it possible to explain what it is or some other name? vapor recovery system?
I havenīt checked the ACS yet, ill do it tomorrow and report results!

The vapors are stored in the charcoal canister that is above the left rear wheel. The purge valve sucks the vapors out of this tank.

Back to the rev problem.
What happens if you operate the throttle linkage under the hood by hand? Have you tried that?
Also look at the traction control throttle body butterfly, it should be wide open.

Ok!

Yep, it is the same as when pressing the pedal, so i guess that the problem isnt anywere between there.
